| Abstract
|
:
|
"This book presents some of the methods used in the theory of amorphous magnetism, from a single standpoint that amorphous magnets have a topologically disordered structure of the type given by the dense random packing of hard spheres. The primary aim is to show systematically the present theoretical apparatus in a form which would allow the reader to use it in investigations of still unsolved problems. Even within these limits, the theory of amorphous magnetism is now a very large subject. This book is not designed to review all the developments in this rapidly developing area. It is primarily intended for the novice in this field, rather than the specialist."--Provided by publisher.
